has gloss | eng: Current sources and sinks are local electrical currents from a location where they cant be detected, into a location where they can be detected (current source) or vice versa (current sink). By analogy to the flow of water, a current source would be like a mountain spring. A source of water flows from a hidden location underground to the surface where it can be easily seen. A sink on the other hand would be like water flowing down a drain. It flows from where you can see it to where you cant. Electric current can have the same basic properties. Current from the "live" wires of an electrical outlet would be a source, while current back along the common would be a sink (although with AC circuits this distinction gets a little murky). |
